[Asterisk-Users] Stupid question about recording prompts

[Brian Capouch]

I am, as this question will make very obvious, not exactly a guru when 
it comes to audio under Linux.

I'd like to record some prompts using a nice microphone and my Ensoniq 
sound card, and then convert them to gsm/wav for use with asterisk.

What Linux command would I use to a) do the recordings, and then b) 
convert them to the appropriate formats?

I know there are sampling/stereo/platform issues, and am hoping to save 
a bit of trial-and-error time.

Thanks.

B.
